Lette/rs Patent No. 104,353, dated Tame A14,1870;

-W IMPRVEMEN-T 1N er..on-tnwssrrms;Amo4 PULvsRIzsRs.

The Schedule referred to hr theme Letton Patent nnfdmaking part ofthe same.

ereuce being .had to the accompanying drawing and to the letters of reference marked thereon.

Drau-ing. Figure l is a ground plan view of my improved de- `Fignrel2 is a central sectional elevation, takenna line :o a: of g. 1.

This invention has for its object Vto provide a device to crush .clods, and for evening the surface of the ground ready for planting ;Y and.

Y It consists'of a revolving roller, vprovided with teeth A.projecting from its exterior surface, in combination The lower edges of these crossdiars are-so formed with a series vof boards ort-planks laid lengthwise with said revolving roller; and secured together-by crossv bars, in 'such a manner that the lirst and lforward bottom plank or strip, shall he secured to the cross-bars, its rear edge being'overlapped by the front edge of the secured plank, thus lforming a s honlden'and so on through the series of planks o1" strips.

Similar letters of reference refer to likeparts in each of the gnres.

To enable others informed in the artto which my invention' relates, to construct and use the same, I will proceed to describe its construction and mode of operation. r

In the annexed drawing forming a part of this spec- .iiicationl A A refer to straight plain pieces oiplank, the under or rearsde of the foremost one being overlapped by the uppery forward side of the second,l and so on through the series, thus forming shoulders e e.

The head plankA' is secured -to the forward edges of the'cross-bars, as' clearly shown in iig. 2.

B B are the cross-bars, to which the planks A A and A are'attached.

llluna... 1 l

' as to be the exact counterpart of the contour of the upper surfaces of the planks A A. Thus constructed,

it willbe 4seen that shoulders bb are formed for the bearings of the rear edges of the parallel planks A A. To prevent the shoulders e-e from wearing off, they are beveled on their faces with some suitable metal, as indicated by the letters ff in fig. 2.

Projecting arms G O are bolted or otherwise suitably fastened to the end cross-bars; within their outer ends the revolving oetagonal toothed roller D is hung,

the ends of said roller being provided with metal bands orthimbles d d, to prevent them from breaking while revolving upon their journals.

E E are tecth,sccured in a permanent manner to the roller D. They project from its exterior-surface, as shown in iig. 2, and are arranged vfrom one end to the other in the form of a screw. v'Having this uniform arrangement upon the roller, 4they become more ef. fectual and. practical in breaking vclods than they would be` if indiscriminately attached.

Any amount of weight may be placed upon 'the' .platform or planks, to hold them and the roller snuglyl to the ground. F is a rod or wire, being the point of draft to which ,the horses are'attached.

I do not confine myself to any particular'4 forniof roller, or to any 'particular arrangement of teeth thereon. y

Having thus described iny invention,

What I claim as new, and desire to secure by Letters Patent of the United States, is-

The combination and arrangement of the toothed roller D and the overlapping planks A A', substanf tially as shown and described.

In testimony whereof I have signed my name to this specification, in the presence of two, attesting 'gitnessea this 14th day of March, 1.870, at Bryan,
